Programa BARRACUDA - Fase I
La SDGPLATIN lanzó el pasado mes de octubre el Programa BARRACUDA, con objeto de conocer el estado del arte de la capacidad nacional industrial relativa al diseño y operatividad de plataformas submarinas no tripuladas. Durante los dos primeros días se probaron varias de estas plataformas en el canal de aguas tranquilas de El Pardo (CEHIPAR), mientras que durante el último día se celebró una jornada de presentación de plataformas, desarrolladas tanto por entidades españolas como por la industria internacional.

El programa está organizado en tres fases:
Fase I: Evaluación de las capacidades ofrecidas por los proveedores nacionales en un entorno controlado de pruebas y preselección de soluciones.
Fase II: Desarrollo de tecnologías necesarias para cubrir las necesidades de la Armada en materia de vehículos submarinos no tripulados.
Fase III: Evaluación de las capacidades desarrolladas en un entorno relevante de pruebas.

Leading the way in multi-hull applications, BMT has released details of its next generation ‘Pentamaran’ platform for autonomous applications. Offering a myriad of applications for defence and commercial innovators, these innovative vessels may be custom configured for military, patrol, intelligence surveillance and reconnaissance (ISR), anti-submarine warfare (ASW) and hydrographic survey work.
The design is the latest from the BMT’s team of expert naval architects and engineers who have been at the forefront of innovative hull design for 34 years. The Pentamaran has been designed to reduce drag as much as possible and tests have proven it offers significant improvements compared to conventional hull forms such as mono-hulls, catamarans and trimaran.
The vessel features a very slender central hull and two smaller hulls or ‘sponsons’ on either side. The sponsons are set one behind the other and when the vessel is operating on flat water, the forward sponsons are not submerged, as they provide roll stability effect in waves only. Compared to a trimaran there is less volume permanently immersed and therefore less resistance through the water.
Martin Bissuel, Business Sector Lead for Specialised Ship Design at BMT comments:
“Our team have carried out extensive work on this. The data gathered through extensive towing tank testing is very compelling. For applications where fuel economy matters, the Pentamaran hull form is more efficient than conventional full forms, which means that using the same engines and the same amount of fuel, it will go further than any other, making it an ideal candidate for autonomous applications. Looking at it from a distance it may resemble a trimaran but that’s where the similarities end.
“The arrangement and careful positioning of the four sponsons makes all the difference. The forward sponsons stay above the water, and only come into action when the vessel rolls, so not only the drag is reduced, but the sea keeping characteristics are improved. Compared to a trimaran hull form, lateral accelerations are lower, reducing g-loadings on the structure as well as the antennae and sensors on deck. The wide deck offers a large working area for multi-role capabilities. It can accommodate payloads or interface with other systems such as unmanned air vehicles.” added Mr Bissuel.
A key consideration, when a vessel is operating autonomously for long periods of time, is the reliability of the propulsion setup which is essential to sustained operational readiness. Our engineers have therefore integrated multiple independent power sources to increase reliability as well as survivability.
QinetiQ leads next phase of unmanned systems exploitation
ECA Group has been awarded a significant export contract to modernize robots dedicated to naval mine warfare, the company announced on 4th May.
This contract, worth around € 20 million will last over 48 months and will allow to modernize the mine clearance capacities of the customer, a Navy, in order to improve their performance against sea mines. The evolution of the mine threat in maritime areas is a current and growing concern for many countries.
For 50 years, ECA Group has been supplying navies all around the world with unmanned systems for underwater mine clearance. The contract awarded in 2019 by the Belgian and Netherlands navies, for the renewal of their mine countermeasure capacities with innovative drone systems, has confirmed ECA Group’s innovation capacity over the decades.
This new modernization contract confirms ECA Group’s capacity to push forward existing underwater mine clearance systems and bring them closer to the performance of the most recent ones. ECA Group is particularly proud of the trust placed in its expertise and solutions by navies worldwide. A trust renewed by this client already equipped with ECA Group drones for several decades.
